Alarm Lock 250XUS28 – Frequently Asked Questions

1) Does the Sirenlock 250 exit alarm lock the door, or is it only a siren?
It does both. The 250 is a panic alarm deadbolt device, so it secures the door with a deadbolt and sounds a 95dB dual tone siren when someone pushes out. The deadbolt design meets relatching requirements while still giving instant egress in an emergency, which is the point of an exit control lock: the door stays secured against casual use but nobody is ever trapped behind it.
2) Is the Alarm Lock 250 exit alarm hardwired or does it need power run to it?
No power run required. The Sirenlock 250 runs on a 9V battery and gives an audible low battery warning when it needs changing. That is what makes it workable on a back-of-house or stockroom door where there is no circuit nearby and no budget for an electrician.
3) Is the Alarm Lock Sirenlock 250 UL Listed and does it meet ADA?
UL Listed, and the 250 is stated to comply with UL, CFM, ADA and NYC housing requirements. For an institutional or multi-family buyer that is the combination that usually decides it, particularly the NYC housing piece on apartment stair and roof doors.
4) What is the difference between the weatherproof and non-weatherproof Alarm Lock 250?
The 250 is sold in two builds, weatherproof and non-weatherproof, and you pick on where the unit sits. Anything exposed to the outside face of the building, a roof door, a loading dock, a gate, wants the weatherproof version. An interior stair, corridor or stockroom door takes the standard non-weatherproof unit. Both are the same 95dB dual tone exit alarm otherwise.
5) What is the closest alternative to the Alarm Lock Sirenlock 250 exit alarm from another manufacturer?
The Detex EAX-500 is the closest cross-brand equivalent. Like the Sirenlock 250, it is a battery powered surface exit alarm for commercial exit doors, and it sounds a 100dB piezo horn where the Sirenlock 250 uses a 95dB dual tone siren. Both are UL Listed style exit control devices intended for the same job: deterring unauthorized use of an exit door while leaving instant egress available. The Sirenlock 250 comes in a US28 aluminum finish and in weatherproof and non-weatherproof builds, so an exterior opening can be covered with the same model family.
6) I need an exit alarm that can be turned off with a key at the door. Sirenlock 250 or Detex EAX-500?
For key control at the door, the Detex EAX-500 is supplied with a cylinder lock, so authorized staff can silence or shunt the alarm at the device with a key. The Alarm Lock Sirenlock 250 is a panic alarm deadbolt device with selectable alarm duration, set either to a 2 minute cutoff so the siren silences itself or to constant alarm until it is reset. If a facility wants the alarm to time out on its own rather than depend on someone arriving with a key, the Sirenlock 250 covers that; if every activation must be cleared by a keyholder, the cylinder on the EAX-500 is the reason to choose it.
7) I need to standardize exit alarms across a facility with ADA and NYC housing requirements. Which one meets those?
The Alarm Lock Sirenlock 250 is UL Listed and states compliance with UL, CFM, ADA, and NYC housing requirements, and it meets relatching requirements while providing instant egress. For an institutional or multi family portfolio being written against a code checklist, that named compliance list is the reason to standardize on the 250 rather than the Detex EAX-500, which is a battery powered exit alarm with a cylinder lock and is specified around its key control at the door.
8) Can the exit alarm siren be set to shut itself off, or does it run until someone silences it?
Either way, it is a setting you choose at install. The Sirenlock 250 has selectable alarm duration: a 2 minute cutoff, or constant alarm until it is reset. Facilities with staff on site usually run constant so the horn keeps pulling attention; a retail back door on an unstaffed shift is often set to the 2 minute cutoff so a false trip does not run all night.
9) What else could I use instead of the Alarm Lock 250 exit alarm, and how is it different?
The Detex EAX-500 is the other battery powered exit alarm we carry in this class. The EAX-500 comes with a cylinder lock and a 100dB piezo horn, so it is keyed at the unit itself and puts out a sharper piezo tone. The Alarm Lock 250 is the deadbolt style device with a 95dB dual tone siren. Choose on how you want it controlled: cylinder key control at the device on the Detex, deadbolt exit control on the 250.
10) Which exit alarm should I put on an exterior door that gets weather?
Specify the weatherproof build of the Alarm Lock Sirenlock 250. The 250 is offered in weatherproof and non-weatherproof versions of the same device, so an exterior rear or side egress door and an interior stock room door can both be covered by one model with one set of install and reset procedures for staff. The Detex EAX-500 with cylinder is a battery powered exit alarm as well, but the weatherproof option is what makes the 250 the one to write on an exterior opening.
11) Does the Alarm Lock Sirenlock 250 need a power supply run to the door like a hardwired alarm?
No. The Sirenlock 250 runs on a 9V battery with an audible low battery warning, so no power has to be pulled to the opening. The Detex EAX-500 is battery powered as well, so neither of these two requires a circuit at the door. That matters on retrofit work in occupied buildings, where the difference between a battery device and a hardwired one is whether an electrician has to be scheduled at all.
12) Will an exit alarm like the Sirenlock 250 lock the door and replace the panic hardware on it?
No, and this is the substitution that gets returned. The Sirenlock 250 is a surface mounted panic alarm deadbolt exit control device that secures and monitors an exit door and releases for instant egress; it is not a rim or mortise panic exit device that carries the crossbar on a rated fire door assembly. The Detex EAX-500 sits in the same category, an exit alarm rather than exit hardware. If the opening needs a listed panic device for egress capacity or a fire rating, an exit alarm of either brand is an addition to that hardware, not a replacement for it.
13) Which exit alarm is louder, the Sirenlock 250 or the Detex EAX-500?
The Detex EAX-500 sounds a 100dB piezo horn and the Alarm Lock Sirenlock 250 sounds a 95dB dual tone siren. The 250's dual tone pattern is a different signal character rather than a single steady horn tone, which carries differently in a corridor than in an open sales floor. For a small retail space or a corridor with hard surfaces, either signal is well past conversational level; in a noisy industrial bay, the higher output of the piezo horn is the specification difference to weigh.
14) Will the aluminum finish on the Alarm Lock 250 match the rest of my door hardware?
The Sirenlock 250 comes in US28 aluminum, a clear anodized aluminum tone. It reads alongside the aluminum storefront doors and mill finish frames you find on most commercial back and side exits, and next to satin chrome and brushed aluminum trim it is close enough that nobody notices. Against bright brass or oil rubbed bronze it will not match.
15) Is the Sirenlock 250 rated for commercial use or is it a residential exit alarm?
Commercial. The 250 is built for office buildings, retail, schools, healthcare, industrial plants and multi-unit residential properties, which is why it carries the UL Listing and the NYC housing compliance rather than being a plug-in door chime. If you are alarming a stair door in a building you manage, this is the right class of device.
16) Can one exit alarm model cover both single doors and a pair of doors, or do I need different parts?
The Alarm Lock Sirenlock 250 is a non handed surface mount device that suits single or double door configurations without complex door modification, so a property manager ordering for a mixed set of openings does not have to split the order by handing or by leaf count. The Detex EAX-500 is the peer battery powered exit alarm to consider alongside it, supplied with a cylinder lock. Ordering one non handed model across a building keeps the spare parts and the staff instructions to a single item.
